w32.vrabat virus pop up

I am using Trend Micro 10.0.1265 on my desktop PC running Windows 10 Home Edition. Lately, I have been getting pop ups saying that I am not using the most recent version of Flash (Windows 10 doesn't use it) or I have w32.vrabat virus and to call a number that is displayed on the pop up. It happens most often when trying to launch Edge (my default browser), but also happens when I launch some of my Windows 10 apps. I have tried running a full system scan several times, but can't seem to get rid of it. Any advice?

Thanks for letting us know this issue. Per your description, the pop-ups you're seeing could also be due to Potentially Unwanted Applications (PUA), software that were installed along with other free software install. Please take a look at the doc below to check if you have any software installed that look suspicious.
